Ironically, both actors' character's direct relation as well as their role and involvement in their superhero children's' lives are quite opposite. Henry Allen is Barry Allen's biological father and was wrongfully arrested when Barry was a child, which led to Barry growing up without him and could never see him outside of visits to his prison, until he was finally released. Eliza Danvers on the other hand is Kara Danvers' adoptive mother who Kara spent most of her life with (if one doesn't count the 24 years she spent sleeping in the Phantom Zone), and heavily influenced Kara's upbringing and blending into the human lifestyle.

Shipp also provided the voice for Eobard Thawne in the animated series Batman: The Brave and the Bold.
